This is a very, very good purchase. I use it to carry my TEN-SCTE around and it has plenty of space, and then some. I can carry my truck, laptop, and my old chassis (I upgraded to the MIP Pro4mance) all in the main compartment. It can hold my set of 6 Integy screwdrivers and quite a few others in the bottom pocket. It can hold a max of 8 SC tires in the side pockets. The controller compartment is a little small, but my Spektrum DX3E is fairly narrow so it fits fine. The only real complaint I have is that it is a bit heavy for a backpack, but most 4WD SC's are upwards of 6lbs. That aside, I highly recommend buying this bag.
